3M super duty rubbing compound and a wool pad on a rotary polisher. I was a little nervous that I would burn through the gelcoat pretty easily with the rotary, but I have to say that it was harder to cut than i thought. I just kept the moving the rotary around and made several passes.

Followed it up with 3M finesse it, but really all the cutting was done and this just seemed to remove any small scratches that may have been left from the wool pad.
